' LIFT AND FORCE PUMP.

SPECIFICATION forming part of Letters Patent No. 547,162, dated. October 1, 1895.

Application tiled December 3, 1892. Serial No. 454,012. (No model.)

.To ctZZ whom t may concern,.-

Be it known that I, JAMES W. WHEELER, a citizen of the United States, residing at Centralia, Lewis county, State of l/Vashington, have invented a new and useful Lift and Force Pump, of which the followingisaspecilication, reference being had to the accompanying drawings as a part hereof.

The objects of my invention are to eonstruct a force-pump by means of which one may obtain a steady head or flow of water, to have the respective parts of my pump easy of access for repair or otherwise, to adapt the pump to serve and act as a ventilator for the well or cistern, and, lastly, to render the pump antit'reezing, all of which objects I attain, as hereinafter shown, by means of the mechanism illustrated in the accompanying drawings, above referred to, the figures in which represent as follows:

Figure l is a vertical section of my invention showing its component parts. Fig. 2 is a vertical section of one of such parts, which I will hereinafter term air-chamber plunger; and Figs. 8 and 4 are respectively a bottom view of such air-chamber plunger and top view of the suction-plunger.

Referring now to the letters, A represents the case, in the lower end of which is attached a cylinder B, in which my air-chamber and suction-plungers operate, said cylinder B having an outlet h and suction-pipe O eX- tending into its lower end. The outlet b should tap the cylinder B at a place about two-thirds its length from the bottom. c is a check-valve to retain the water in said cylinder B when the plungers descend. The construction of the said air-chamber plunger E and suction-plunger F is shown in the enlarged section thereof in Fig. 2. The airchamber plunger E consists of a cylinder G, (made out of a piece of boiler-tube or other suitable materiah) on the upper end of which is secured a cap H and to the lower end a base or plate h', these parts being secured together by means of a tube t', threaded at both of its ends and screwed in the threaded central perforations k Zt', provided in said cap H and plate h. The tube likewise provides a passage-way for the rod Z to operate in. The under side of the rim of the cap H and the rim of the upper side ot' the plate h are each provided with an annular groove in which to seat the ends of said cylinder Gr and make the attachments air-tight by means ot1 packing. (Not shown.) The plate h has an annular flange h2 beveled on its interior and projecting downward, and in this is another plate mhaving an annular flange n', projecting upward and beveled on its exterior to correspond with the beveled llange h2 of the plate h', between which beveled flanges the leather packing or bevel-gasket o is secured, the plates h and n being bolted together by means of screw-bolts p, and each of said plates having four perforations h3, (see Fig. 3,) located above each other to leave a passageway through which the water can enter the cylinder G and be expelled out again. The air-chamber plunger E is suspended in the cylinder B from the handle or lever D by means of a rod q and connections q q, the latter having lug-pins Q3 engaging in the ears h4 provided on the cap H. The rod Z is also attached to said handle or lever D, extends through the tube t ofthe air-chamber plunger E, and carries the plunger F on its lower end.

r represents packing for the rod l, which must be provided at either the lower or upper end of the tube t'.

The plunger F consists of a plate f having an annular flange f2 beveled at the exterior and conforming with the beveled flange of the cap f3, these parts being secured together between nuts screwed on the threaded end of the rod Z, and hold between them the packing or bevel gasket f4, and s represents a suction-valve. The plate f and cap f3 have several perforat-ionsf (see Fig. 4) corresponding with each other to form water-passageways.

I represents brackets alr'ording a hearing for the handle or lever D.

The rod q, suspending the air-chamber plunger, must be so proportioned in length and attached to the lever D that in making the downward stroke in the cylinder B the airchamber plunger will reach nearly, but yet not quite, to the outlet b. By this arrangement the suction-plunger F will describe twice the distance ot' the air-chamber plunger in the cylinder B, and thus I obtain my double action.

The cylinder B is continually lled with ICO water, and on operating my pump each upstroke or rise of the plungers forces one-half of the bulk of the water lifted out of the outlet-pipe b', while the other half follows the air-chamber plunger E, and entering in part into such air-chamber E through the perforations h3 in its plunger, the quantity of water so entering being in proportion to the force applied. The -water forced into said airchamber compresses the air therein confined to a diminished bulk, the reflex of which expels the water out of such air-chamber plunger in the downstrolie as the pressure at the outlet L decreases, and thus the flow of water while changing the strokeis maintained. As soon as pumping is stopped the water in the delivery-pipe b, not being restrained by any check-valve, will seek its level and overflow the top of the cylinder B, and as this is below the platform of the well or oistern the pump is not subjected to the immediate influence of cold weather, and, therefore, becomes antifreezing. The overflow of water in the cyl- Such ventilation is further assisted by an opening or openings provided in the side of the casing A, between the platform and top of cylinder l5, and the opening of the handleslot.

Having thus fully described my invention, what I claim is as follows:

In a lift and force pump, the combination with the casing, the cylinder telescoping in the lower end thereof and provided with a check valve and an outlet near its upper end, of the vertically movable air cylinder having openings in its lower end, the central vertical tube, the handle connected with said cylinder, the plunger rod also connected with said handle, and the valved plunger secured to the lower end of said rod, the construction being such that the plunger will have a longer stroke than Ithe air cylinder, substantially as and for the purpose specified.

In testimony whereof I have hereunto affixed my signature in the presence of two witnesses.

JAMES W. YVHEELER.
